EP1038491A2 - Floor cleaning device - Google Patents

Abstract

The floor cleaner has a handle (2) pivotably mounted on a housing, whereby for the pivoting connection is produced by two journals engaging corresponding. apertures. The pivotal connection has different axial play for each different position. A first and/or a second journal (3,4) is/are made in the form of a pipe connector.

Description

The invention relates to a device for cleaning floors according to the preamble of claim 1.

With floor care devices are usually rigid in or on Housing integrated handles used. With swiveling One would first grip on a fastening with a separate and especially fixed by special measures Think axis. A handle attached in this way would, however, be assembly and costly.

A wet and dry vacuum cleaner is known from DB 197 03 014 A1, a pivoting handle is attached to the housing, the has two pins, which in corresponding recesses intervention.

The object of the invention is a device for floor cleaning specify with a pivotable handle, the Handle is simple, quick and inexpensive to assemble and a particularly secure connection at least in the carrying position is guaranteed with the device.

This object is solved by the features of claim 1. Appropriate configurations result from the features of subclaims.

According to the invention it is provided that for the production the swivel connection two in corresponding recesses engaging pegs provided on the handle are. This eliminates the need for a thru axle become. The proposed attachment of the handle enables easy assembly. You only need the cones are brought into engagement with the recesses.

A first and / or a second is / are advantageously Cones designed in the manner of a pipe socket. This saves Material and therefore weight.

According to a further advantageous embodiment is on the edge at least one journal projecting in the axial direction cam-like elevation provided. Can on the housing a first recess for receiving the first pin and a second recess for receiving the second pin is provided his. It is expedient for the first and / or second recess each provided a detent spring. The the aforementioned features enable a particularly simple Assembly of the handle. He can be in a suitable position simply snapped onto the housing.

Schnapp- oder Rastmontage" darf die Länge der Achse nur geringfügig größer sein als die lichte Breite der Achsaufnehmung in die die Achse eingeschnappt werden soll, so daß unter Ausnutzung der Elastizität des Materials das Einschnappen gerade noch möglich wird. Der Nachteil einer solchen Rastverbindung besteht darin, daß die Gegenlagerfläche der Achsaufnehmung relativ klein ist, so daß der Griff beim Tragen leicht wieder ausschnappen kann, wenn der zu tragende Gegenstand, wie bei einem Staubsauger, ein relativ hohes Gewicht aufweist.For the

Snap or snap assembly "the length of the axle may only be slightly larger than the clear width of the axle holder into which the axle is to be snapped, so that snapping is just still possible using the elasticity of the material. The disadvantage of such a snap connection is that that the counter bearing surface of the axle receptacle is relatively small, so that the handle can be easily snapped out again when the object to be carried, as in a vacuum cleaner, has a relatively high weight.

Therefore, after a further advantageous training Invention provided that the handle in a first position with a first axial play and in a second position movable with a second axial play in relation to the housing can be, the second axial play smaller than that first axial play is. This makes installation easy of the handle in the first position. In the second Position, e.g. a carrying position, it will still be safe held on the housing.

According to a further embodiment, one of the recesses an abutment corresponding to the cam-like elevation intended. The cam-like elevation is expedient attached so that when you move the Griffs from the first to the second position on the abutment runs up, so that the handle axially in the direction of the second recess is moved. So when placing the Handle in the second position the axial play on simple Way will be automatically decreased.

The handle is advantageously made in one piece from injection molded Made of plastic. This further lowers manufacturing costs. The housing can of course also be made of several shell-like made from injection molded plastic Be housing parts assembled. In this case the handle is attached to one of the housing parts.

An exemplary embodiment is explained in more detail below with reference to the drawing. Show it:

In Fig. 1 is an upper housing half-shell 1 Vacuum cleaner attached a handle 2. The handle 2 is here in a first - folded - position S1 (rest position). In Fig. 2 the handle 2 is in one second - unfolded - position S2 (carrying position).

As best seen in FIGS. 3 and 4, the preferably made of injection molded plastic Handle 2 has a first pin 3 and a second pin 4 on. The first 3 and the second pin 4 are in shape here a pipe socket. The first pin 3 points on Edge of an axially projecting cam-like elevation 3a. The second pin 4 is at least in sections on its edge bevelled with AS.

On the housing half-shell 1 are a first detent spring 5 and a second detent spring 6 attached. The first 5 and the second detent spring 6 delimit a first recess A1 or a second recess A2, in which the first 3 and the engage second pin 4.

The first 5 and the second detent spring 6 are expediently made together with the housing half-shell 1 in one piece from injection-molded plastic. The detent springs 5, 6 are elastic. The term Latching springs "is to be understood in such a way that, on the one hand, separate spring elements can be introduced into the housing shell, which form an independent functional part and, for example, can also consist of a different material than the housing shell Latching springs "can also be designed as a special version of the housing shell, ie can be injected with the housing shell in one operation. Finally, but not ultimately, they can Latch springs "consist only in that part or the entire housing shell acts elastically or, in other words, that without any additional measures, only the entire elasticity of the housing shell is used to snap the gripping axes.

As best shown in Fig. 4 - with the clarity only the lower handle part is shown - can be seen the cam-like elevation 3a has sloping flanks. If the handle 2 is in the second position S2, the cam-like elevation 3a on one on the first detent spring 5 attached abutment 7. The repository can of course also the wall of the corresponding axle bushing or axle support.

The function of the device is as follows:

To assemble the handle 2, it is brought into a position which is essentially the first position S1, in any case but not the carrying position. It will be first the first pin 3 engages with the corresponding one Recess A1 brought. In this position the cam-like elevation 3a of the first pin 3 not on the abutment 7 on. The first spigot can be longer than the second cone. Then the second pin 4 against the corresponding detent spring 6 pressed. As a result both the first 5 and the second detent spring 6 are pressed apart, so that finally the second pin in the Recesses A2 clicks into place. The AS chamfer ensures that for easier snap-in. In the first position S1 are the pins 3, 4 with a game SP1 between the two Latching springs 5, 6 added.

When the handle 2 is about 90 degrees to the second position S2, i.e. the cam-like comes into the wearing position, is pivoted Elevation 3a in contact with the abutment 7. The Handle 2 is axially in the direction of the second recess A2 postponed. Since the first journal 3 is relatively long, but it is still of sufficient length the detent spring or formed by the axle holder A1 Counter bearing.

The first pin 3 and the second pin 4 are in the embodiment shown directly on the first 5 and the second detent spring 6 or on the axle bushings. In the second position S2, a second game SP2 is zero. The pins 3, 4 engage behind in the second position S2 Latching springs 5, 6 completely. So is in the second position S2, the carrying position, a secure hold of the handle 2 on the floor care device guaranteed.
